Having trouble with Ionic Tinder for X

I have been attempting to experiment with the Tinder for X card stack, but have been having some issues. I followed this tutorial to help put them in my app: https://blog.nraboy.com/2015/01/making-tinder-style-swipe-cards-ionic-framework/

Every time I try to do this I get the same white screen with a h1 header on the top left and a single card that isn’t able to move, but appears to be part of the background. I attempted to upload a picture to show this, but every time the upload fails. I have the ionic-contrib-tinder-cards folder in my project (including the collide library), but only the single square is showing up. Anybody have any possible suggestions?
